According to the automatic water cut-off device 10, the ejector rod 100, the ejector assembly 200, the rear mold core 300 and the hook needle 400 are arranged, the ejector block 240 is used for sliding in the first sliding groove 301 until the ejector block is abutted to the injection product 20, the ejector block continues to push outwards and push out the injection product 20, at the moment, as the hook needle hooks the water gap, when the ejector block continues to apply an outwards pushing force to the injection product, the connecting position of the injection product and the water gap is broken, the injection product is separated from the water gap, and the first ejection of the injection product is realized, so that the injection product is separated from the water gap. The pushing block 240 is further configured to push and push the gate 30 when sliding in a direction close to the second sliding groove 302, and in a process that the pushing block slides outward in the second sliding groove, the pushing block is pushed against the gate, and when an outward pushing force is continuously given to the pushing block, under the action of the pushing force, the gate is separated from the crochet hook, that is, the gate is pushed out to realize demolding, that is, the second ejection of the injection molding product is realized, so that the injection molding product and the gate realize automatic demolding operation.
In order to prevent the water gap from being communicated when the water gap is ejected for the first time, the injection product is ejected together, the water gap and the injection product can be separated only by manual treatment after the injection mold is ejected, for example, the crochet needle comprises a needle rod, a back hook part and a plurality of connecting bulges, the first end of the needle rod is fixed with the back mold core, the second end of the needle rod penetrates through the sliding hole, the back hook part is arranged on the second end of the needle rod, the back hook part is of a cone structure, the diameter of the back hook part is gradually increased from being close to the needle rod to the direction far away from the needle rod, an inner flow ring groove is formed at the connecting position of the back hook part and the needle rod together, and each connecting bulge is respectively arranged on the bottom surface of the back hook part and is distributed in an even scattering shape.
For example, the gate is provided with an embedding groove, the bottom surface of the embedding groove is provided with a plurality of alignment grooves, the gate is provided with a limiting ring body at the edge position of the embedding groove, thus, the hook part is embedded in the embedding groove to enable the hook needle to hook the gate, and then the connecting protrusions are embedded in the alignment grooves in a one-to-one correspondence manner, so that the contact area between the hook needle and the gate is increased, the viscous tension of the hook needle on the gate is further increased, finally, the limiting ring body is clamped in the inner annular groove to enable the gate and the hook needle clamp to be more stable, so that when the push-out block is ejected for the first time, the injection molding product is subjected to an upward force, and the gate is subjected to a smaller tension of the injection molding product relative to the tension of the gate, namely, the water gap is not easy to eject out when the water gap is ejected out for the first time, and the water gap can not be ejected by the ejection block until the ejection block is directly ejected to the water gap due to the direct force of the limiting ring body.
Further, for example, the maximum diameter of the hook back portion is slightly smaller than the bore diameter of the sliding hole, which helps the ejector block push out the nozzle when the ejector block pushes against the nozzle, so that the nozzle is not pushed by the ejector block; for another example, the edge of the back hook part is provided with a guide surface, which helps the water gap to be more easily removed from the hook needle when the pushing-out block pushes the water gap.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
